To reinforce the side frames and the Similar reference-numerals in the several transoms, laterally extending lugs 16 16 figures indicate similar parts. may be provided to rest upon the top of the 4 5 In the present embodiment of my invention upper flanges 19 19 of the channel-bars 11, an

These anglebraces 40 also constitute supports for the brake-rigging.

Immediately beneath the upper casting 16 is provided a lower casting 25, having ofl set flanges 26 26, between which the lower trussbar 3 rests. Upon the uppersurface and at each end of the casting'25 are provided the upwardly-extending shoulders 27 27, webbed, as at 28 28, a substantially right-angled recess 29 being formed adjacent each shoulder, leaving an abutting flange 30 upon the outer side of said casting. Into these recesses 29 are adapted to be riveted the ends of theZ-bars 12 12, the ends of said bars abutting against the flange 30 and the inwardly-extend ing flange 31 resting in the lower portion of the recess 29 in such manner that the upper surfaces of said flanges 31 and the central or intact portion of the casting 25 will be flush or continuous.

The abutting flanges 13 14 of the channel and 2 bars, respectively, being united by the rivets 15 or other suitable means, it will be seen that the transoms connecting the side frames 1 1 are united by the end pieces or castings 16 and 25 to form one solid unitary structure capable of resisting to the maximum degree all forces acting upon the side frames to produce a distortion or twisting action between the side frames and transoms. While the composite transom produced by the channel-bar and Z-bar is preferred as possessing the maximum rigidity, it will be understood that a transom may be produced in accordance with my invention composed of a single Z-bar, the upper flange thereof correspending with the flange 19 of the channelbar and the lower flange corresponding to the lower flange of the Z-bar 12; but while this construction may be adopted it would not possess the additional rigidity secured by the flanges 13 14 of the channel and Z bars, respectively. These transoms 9 10, respectively, together with the upper and lower seats or castings 16 25, respectively, are firmly secured in the side frame 1 1 between the upper and lower truss-bars 2 3, respectively, by the tie-bolts 24 passing also through the bracerod connecting the axleboxes. Interposed between these transoms 9 10, respectively, is a bolster 32, comprising in the present construction an arched channel-beam 33, upon the top of which, intermediate its length, is secured the pivot-block 34, about which the truck turns as its center. Near each end of said bolster are provided the side bearings 35 35 of any suitable construction. Depending from this bolster at the center is a bridge-piece 36, beneath which passes the truss member 37. anchored at each end of the bolster in any suitable manner. In the present embodiment the ends of this truss member are bent back, as at 38, embracing the upturned extremities 39 of the beam 33 of the bolster, rivets or the like being passed through to secure the parts together.

At each end of the bolster is provided a spring-seat 41, so disposed upon said bolster that the ends thereof are immediately adjacent the inner faces of the castings 1616, whereby longitudinal thrust of the bolster will be received and lateral movement pre vented by the castings 16 16. These end pieces 41 41 are of such a width as to slidingly rest between the transoms 9 10, respectively, in such a manner as to transmit the lateral thrust between said bolster and transoms. Beneath these end pieces or supports 41 41 upon the bolster are plates 42 42, comprising spring-platforms. One of these plates 42 is located beneath the supports 41 41 upon the bolster and preferably rests upon and is supported by the inturned flanges 31 31, respectively, of the Z-bars 12 12, rivets or other suitable means being employed for securing said plates in position. Interposed between these spring-platforms 42 42 and the supports 41 upon each end of the bolster are helical or other suitable springs 43 43, adapted to sustain the weight of the car-body and to form a resilient support for the bolster. However,

it will be understood that I do not limit my-' self to the use of any particular form of bolster.

It will be seen from the foregoing that a cartruck is produced from commercial forms, whereby the maximum rigidity is secured within the limited weight and the prescribed cost of manufacture. By forming the transoms of channel and 2 bars united to form a unitary structure and securing the ends of the transoms thus formed in the supporting seats or castings carried by the side frames all forces tending to twist or distort the relative positions of the side frames and transoms are most effectually resisted. The overhanging flanges 21 21 upon the upper castings extending over the edges of the upper flanges 19 of the transoms will transmit the lateral thrusts of the bolster received thereon through the castings 16 to the opposing transom, thereby practically doubling the resisting power of the transoms against lateral thrust of the bolster. End thrust of the bolster is received upon the upper castings 16 and transmitted directly to the side frames, thus avoiding the weakness necessarily resulting from intervening structure.

It is obvious that in the construction of a truck of this character, in which commercial rolled forms are employed, repairs may be readily made by duplicating the parts from stock material.

While I have adopted in the present embodiment of my invention certain details in construction, it of course will be understood that I do not so limit myself, as many modifications and changes might suggest themselves to thoseskilled in the art which could be made without departing from the spirit of my invention.
